Compared to the Global Warming Potential (GWP), the Global Temperature change Potential (GTP) goes one step further down the cause–effect chain and is defined as the change in global mean surface temperature at a chosen point in time in response to an emission pulse—relative to that of CO2. Whereas GWP is integrated in time, GTP is an end-point metric that is based on temperature change for a selected year, t. Like for the GWP, the impact from CO2 is normally used as reference, where AGTP is the absolute GTP giving temperature change per unit emission. Like GWP, the GTP values can be used for weighting the emissions to obtain ‘CO2 equivalents’.
